TEMPE, Ariz. -- Oregon coach Dana Altman is concerned about safety at Arizona State's Wells Fargo Arena after two of his staffers claim an ASU student spit at them at halftime of Saturday's night's game.

Oregon assistant coach Brian Fish told The Oregonian the student spit at him and trainer Clay Jamieson and reported the incident to arena security, but did not want charges pressed.

The incident was addressed and the student had his season tickets revoked, according to an Arizona State official.

Altman said after the Ducks' 747-72 loss it was not a good situation having visiting teams go past the student section on their way off the court at Wells Fargo Arena.

Ducks guard Jason Calliste had a verbal confrontation with at least one student late in the first half.
